However, even in the print gamut of the image forming apparatus, the color may be largely changed by the monitor used by the user, and therefore, it may be difficult to print in the color desired by the user by changing only the color conversion algorithm.
Therefore, as a related art, for example, there has been disclosed a color printing apparatus including: a preview display; a specifying unit configured to specify a color correction object on a preview screen of a preview display; a color correction unit that performs color correction on print data of a color correction target; and a color printer that prints the print image corrected by the color correction unit, and displays the print image in color on a preview screen of a print data preview display transmitted from a Desktop Publishing (DTP) editing apparatus (see patent document 2).
Thus, the user can check whether or not printing can be performed with a desired color tone by observing the preview screen before actual printing is performed.

(working Process of color Change)
Next, a process of changing the color of a specific portion of the preview image displayed on touch panel display 130 in image forming apparatus 100 according to the first embodiment will be described with reference to a flowchart.
Fig. 4 is a flowchart showing a process of a color change process of changing a color of a specific portion based on a preview image displayed on the touch panel display of the image forming apparatus according to the first embodiment.
In image forming apparatus 100 according to the first embodiment, when the color of a specific portion of a preview image displayed on touch panel display 130 is changed, first, as shown in fig. 4, an image is read from a document (step S1). The read image data is stored in the storage unit 150.
Next, a preview image 1310 is generated based on the image data (step S3), and the generated preview image 1310 is displayed in the first display region 1301 of the touch panel display 130 (step S5).
Next, it is determined (selected) whether or not to change the color of the image (step S7).
If it is determined in step S7 that the color of the image is not to be changed, the color change process is terminated. On the other hand, if it is determined in step S7 that the color of the image has been changed, a region for which the color has been changed is identified in preview image 1310 (step S9).
In step S9, the color-changed region specifying unit 191 specifies a region to be color-changed in the preview image 1310.
Next, the similar color image generating unit 192 generates a similar color image 1320 including a similar color corresponding to the color of the specific portion (step S10). Next, the similar color image 1320 is displayed in the second display region 1302 (step S11).
Next, in the similar color image 1320, after the user specifies the color to be changed (step S13), the color of the region to be color-changed is changed to the designated color (step S15).
Then, preview image 1330 after the color change is displayed on touch panel display 130 (step S17).
Thereby, the color change processing of the image is executed.
Since the configuration described above is adopted, according to the first embodiment, image forming apparatus 100 includes document reading unit 110, touch panel display 130, storage unit 150, image generating unit 160, image output unit 170, and control unit 180, and further includes color changing portion specifying unit 191 and color-approximated image generating unit 192, and can display preview image 1310 on touch panel display 130 by control unit 180, select a specific portion of preview image 1310 subjected to color change by color changing portion specifying unit 191, display on touch panel display 130 color-approximated image 1320 generated by color-approximated image generating unit 192, and change the color of a region including the specific portion to the color selected from color-approximated image 1320. Thus, it is possible to provide an image forming apparatus that can easily specify a color desired by a user from the near-color image 1320 and has an excellent user interface when changing the color of a specific portion of an image.
In the first embodiment, by displaying preview image 1330 of the print image after the color change on touch-panel display 130, the print image after the color change can be confirmed before printing, and therefore, the color change desired by the user can be performed without performing wasteful printing.
(second embodiment)
Next, a second embodiment will be explained.
The second embodiment is characterized in that: when the color of an image is changed in an image forming apparatus, when the color selected from the color of a specific portion subjected to color change is changed, the color of the vicinity of the specific portion subjected to color change is corrected.
In addition, the second embodiment is characterized in that: the correction range of the approximate color of the area adjacent to the specific portion where the color change is performed can be set.
Fig. 5 is a block diagram showing a configuration of a main part of an image forming apparatus according to a second embodiment, and fig. 6 is an explanatory diagram showing a Lab color space of an image in the image forming apparatus in a two-dimensional plane.
Note that the same reference numerals are given to the same components as those of the image forming apparatus according to the first embodiment among the components of the image forming apparatus according to the second embodiment, and thus the description thereof is omitted.
As shown in fig. 5, the image forming apparatus 200 according to the second embodiment is characterized in that: the image forming apparatus 100 according to the first embodiment includes an approximate color correction region setting unit 293.
The approximate color correction region setting unit 293 corrects the approximate color of the region adjacent to the specific portion to be color-changed. The approximate color correction region setting unit 293 sets a range of a region (hereinafter referred to as an "approximate color correction region") for correcting the approximate color of the neighboring region of the specific portion to be color-changed.
An example of color correction in the approximate color correction region is shown below.
When expressed in the color space (L, a, B) of the Lab color system, the point a, the point B, and the point C to be changed in color are as follows, as shown in fig. 6.
Points where a color change is desired: a (L1, a1, b1)
Changed points: b (L2, a2, B2)
Points of approximate color: c (L3, a3, b3)
If a correction range indicating which range the color is corrected to is defined as "N", the distance X between a and C in the color space is defined as
[ mathematical formula 1]
The corrected variation Δ C (Δ L, Δ a, Δ b) of the point C is
[ mathematical formula 2]
[ mathematical formula 3]
[ mathematical formula 4]
[ math figure 5]
When X is greater than N, delta L-delta a-delta b-0
In addition, for the correction in the case where the colors of a plurality of dots are changed,
if the dots to be changed in color are a1(LA1, aA1, bA1), a2(LA2, aA2, bA2).
The points after color change were set to B1(LB1, aB1, bB1), B2(LB2, aB2, bB2).
The distances between a1, a 2.. and the approximate color C were set to X1, X2..,
then S is as follows, except for the distance Xi between points Ai and C where Xi > N.
[ mathematical formula 6]
The corrected variation Δ C (Δ L, Δ a, Δ b) of the point C is [ equation 7]
[ mathematical formula 8]
[ mathematical formula 9]
Since the configuration described above is adopted, according to the second embodiment, image forming apparatus 200 includes approximate color correction region setting unit 293 in addition to the configuration of image forming apparatus 100, and thereby, when changing the color of an image, can correct the approximate color of the region adjacent to the specific portion where the color is changed.
In addition, according to the second embodiment, the range of the approximate color correction region is set by the approximate color correction region setting unit 293, and thus the range of the approximate color correction region can be easily set according to the size of the region of the approximate color to be color-changed.
(third embodiment)
Next, a third embodiment will be explained.

In the fourth embodiment, when the color of a specific portion of an output image (print image) is changed, as shown in fig. 10 (a), a preview image 1310 based on image data is displayed on touch panel display 130, and a portion to be color-changed is specified in preview image 1310, as in the first embodiment.
When preview image 1310 is displayed on touch panel display 130, first display region 1301 for displaying the preview image is set, and preview image 1310 is displayed in first display region 1301.
After the user specifies the portion to be color-changed in preview image 1310, as shown in fig. 10 (b), approximate color image 1320 of an approximate color including the color of specified portion 1311 specified by the user is displayed on touch-panel display 130.
The approximate color image 1320 shows approximate colors in a predetermined range.
In the fourth embodiment, as shown in fig. 10 (c), a characteristic image 1350 of an image area 1352 including a specific portion 1311 is displayed in correspondence with the specific portion 1311, which is color-changed, in the preview image 1310.
The characteristic image generation unit 493 generates a characteristic image 1350 corresponding to the determined portion where the color is changed. In fig. 10 (c), a characteristic image 1350 is generated, and the characteristic image 1350 includes an image area 1352 corresponding to the area 1312 of the face portion of the preview image 1310.
For example, the characteristics may be distinguished by a boundary between the region 1312 of the face portion of the preview image 1310 and the background, which has a greatly changed color. The threshold value may be determined by using a distance on the image from the portion where the color change is performed, a degree of similarity of colors, or the like.
In the fourth embodiment, similarly to the first embodiment, a preview image 1330 of the output image after the color change may be displayed in the first display region 1301 instead of the preview image 1310.
Since the configuration described above is adopted, according to the fourth embodiment, image forming apparatus 400 includes characteristic image generating unit 493, and thus, when a specific portion of preview image 1310 for which a color is to be changed is specified at a plurality of locations on touch-panel display 130, a plurality of characteristic images can be generated and displayed in accordance with the specific portion for which a color is to be changed, and therefore, the specific portion for which a color is to be changed can be made clear individually. This makes it possible to easily confirm the specific portion where the color is changed.
In the above-described embodiment, the image forming apparatus is described as an example of an image processing apparatus that changes the color of a displayed image, but the above-described technique may be employed in a terminal such as a Personal Computer (PC) including a monitor (display unit), for example, and image data of a print image may be displayed on the screen of the monitor and color change may be performed on the image data before printing is performed by a printer (image forming apparatus).
